Specicateii of Letters Patent.

T0 @ZZ lio/iom 'it may concern l it known that I, VALTER E. AMBERG, a

eitizieii of the United States. residing at Chicago, in the county of Cool; andState of Illinois, have invented certain new and useful lmpioveinents in Staples for FencesI and other Purposes, of which the following` is a speciiication. A

The object of my invention is the prox-i sion of a substantially U-shaped staple provided with legs and so fashioned that when the staple is driven into a hole through a hollow metallic fence post or plate of limited thickness the'- legs will frictionally bear against the inetal defining the hole and cau-se the said legs to cross each other and spread apart in planes approximatelyparallel with or slightly oblique to the plane of the base of the staple, and hold the wire or rod passing through the staple to the said post or plate, and which staple when entirely seated shall lock the wire so it cannot move relativel to the post.

It is desirable tohold the wires of a wire fence taut between adjacent posts and not merely between end posts or Corner `posts or posts where a gate is located, so that when undue strains are imparted to the wires under the action of the displacement of the posts by frost .or by the pressure of cattle against the wires 0i' by the weight in climbing the fence the strains will not be transmitted to said end, corner or gate posts( only.

lith common means heretofore used for securing wires to hollow metallioposts it has been found difficult to lock the wires iniinovably to adjacent posts. My improved staple is designed to obviate this objectionable feature of construction and, to lock the wires in taut positions between adjacentposts, thus relieving the-end and corner posts from undue strains.v

My invention consists generally of a staple of a substantiallv U shape with the legs offset from the plane of the base and bent toward eachother so the pointsl will lie in a plane at an angle to the 'plane of the base and the ends spaced apart a distance suflicient to allow the staple to be passed over a wire; and it consists more specifically in certain other novelties of shape, all as specified',

hereinafter and. set forth in the claimsf,v

TWhile the invention adinitsof various enioodiinents and may be applied insecuring a wire or rod or tube to a metallic plate with a. hole through it, l i Y lrawing its with n e being con.,

li'iguro l shows a hollow inetallic fence post witl wires secured to the saine and locked in fixed positions by my improved staples. Fig. 2 is a part horizontall section of Fig. 1 on line mex, showing y"one-'alf the y y wires locked to the post. Figs. 3, et, andja, ,y are views on enlarged scales illustrating theTV principle of tlie application of the staple, F 3 showingY a horizontal sectional if'iewof' a plate oi' post with the pointed ends of the staple entering the hole therethrough and dotted lines another advanced position of -the staplepfig. l showing a side elevation View of Fig: 3 with the points of the staple in the hole; and Fig. 5 showing a. vertical sectional View, atthe right the staple about to be driven into a hole in a plate or post, and at the left 'a wire or rod surrounded by the staple and to beheld in place against a post or plate, the dotted lines indicating the position of the staple when seated. Fig. illustrates the staple about to be driven into an oblong or ellipticallv lshaped hole in a plate or post, the ends of the legs in this instance lnot being pointed' but the legseaoh of a spiral shape.

Referring to Figs. 3,' 4 'and 5,'the numeral l designates the staple; 2, the base of the staple; 3, the legs; 4, the pointed ends of the" i les; `and 5 a plate or section of a metallic post with a. 'hole-6 therethrough The legs are eachl offset or oppositcly bent or twisted so the extreme ends will lie at opposite sides of an imaginary plane, see dotted ling-Fig. 3, passing through the base of thefstaple and both legs where they spring from the base, and lie -in a plane at an angle to said imaginary plane, and preferably7 the bend or twist of each leg is of a spiral shape from the basey to the end of the leg. The end of each leg has a point-4 preferably formed by cutting the nietal on a plane oblique tothe length of the leg sov as to format the saine time the beveled surfaces' 7, 7, which surfaces are on the outer surfaces of the legs or oppositely disposed to each other. 'YT he fashioning of lthe staple'should be such that a wireor rod may be passed between the ends tothe base with or slightly oblique to the plane of the base of the staple, obviously certain relativey dimensions of the hole and staple are necessary. v

When the hole 6 in the plate or post is round or polygonal the diameter thereof should be less than the distance B of the staple, so the metal of the legs Will friction'ally enga-ge the metal deining the hole, as at F, F, Fig. 5. It,ltherefore,follows that for use in a round hole the ends of the legs should 'be made pointed by forming the beveled surfaces 7, 7, so as to start the staple in the smallest hole possible to use in order that the maximum amount of spread of the legs may be obtained when the staple is Seated as shown by dotted lines in Fig. 5 at Gr, G. Obviously, the action of the staple will be the same when driven into a square -or polygonally shaped hole. Therefore, I do not limit the scope of the invention tothe exact shape of the hole.

When the hole in the plate or post is made of an oblong or elliptical shape, as show/nat 8, Fig'. 6, the hole maybe longer than the y distance over the legs fof the staple so the vends' of the legs may enter the hole Without being sharpened. However, it is desirablev that as small a hole as practical shall be used relative to the dimensions of the staple so as to insure the maximum spread of the lembodied in coimection with a hollow nietallic fence post and Wires. In these figures D is the post, l0 the holes, 11 the wires, 12 the staples, and 1 8 the legs of staple. It will be observed that when the staple is seated the metal of the Wire at la has been upset or 'bent and forced into the hole sailiciently to lock the Wire so it is practically immovable relative to the post, consequently in a fence so constructed the wires between adjacentA posts will be taut and strains imparted to the Wires will be transmitted. substantially only to adjacent posts.

llhat I claim is:

l. A metallic staple of a substantially U shape having the legs Aoffset or bent side- 'vvise and toward each other so the ends of the legs Will lie in a plane at an angle to the plane of the base, a space being` 'provided between the ends of the legs for vthe passage of a wire. v l l 2. A metallic staple of a substantiall,iT U shape having the regs oiiset or bent sidewise in opposite directions and toward each other and the ends oi said legs provided uf'ith beveled surfaces forming points.

3. A4 metallic staple of a. substantially U- shape and having its legs pointed and oil'sct `or bent sidewise and toward each other so the points pf the legs Will lie in a an angle to the plane of the base.

In testimony whereof I ailixmy signature in presence of twp Witnesses.
